DESCRIPTION
The PGA102 is a high speed, digitally programmable-
gain amplifier. CMOS/TTL-compatible inputs select
gains of 1, 10 or 100V/V. Each gain has an indepen-
dent input terminal, providing an input multiplexer
function.
On-chip metal film gain-set resistors are laser-trimmed
to provide excellent gain accuracy. High speed input
circuitry allows multiplexing of high speed signals.
The PGA102 is available in 16-pin plastic and ceramic
DIP packages. Commercial, industrial and military
temperature range models are available.
